[Extracting info from a text file]

I am pretty new at php so I think I need a little bit more information - can anyone either direct me to a tutorial or a script that I could customize?

You can use explode() 2 times... But I would rather create a multidimensional array:

[code]
$data = array (
   '0' => array (
      'img'   => 'image1.jpg';
      'descr' => 'information about this one'
    ),

   '1' => array (
      'img'   => 'image2.jpg';
      'descr' => 'information about the second one.'
    ),
);[/code]

serialize() it and store in a txt. It's more accurate.

[Extracting info from a text file]

Hi there,

I'm setting up an online portfolio and would like to know what the best way to pull up image descriptions would be. I've seen it done before by setting up a text file like this:

image1.jpg; information about this one
image2.jpg; information about the second one.

then when you load image1.jpg onto the page, you also pull up "information about this one" into the page.

Right now I just have a navigation set up where the link is to index.php?id=imagename

and then I load the appropriate image like so:

[code]$first = array('home','about','contact', 'work');

if (in_array($_GET['id'], $first)) {
          print '<img src="http://' . $_SERVER['HTTP_HOST'] . '/images/' . $_GET['id'] . '.jpg" alt="title" />';[/code]

I'm not even sure what the process would be called so I haven't really been able to do research on it.

I know I could set up something using line numbers and call the images by numbers that calls up the appropriate line number - but I'd prefer to have it know which line to pull based on the variable $id.
